yarte_config is the crate in charge of parsing the configure file, yarte.toml,
to a rust object that will later be treated in the rest of the crates.
Right now a Yarte configuration file can have the following:

main (general configuration - optional): with attribute

dir: name of template directory. If no value is given, a default directory
templates will be used. If the defined directory is not found, an error
will prompt.

debug: type of output of debug mode. The code and/or ast generated by Yarte
can be visualize, to do so, at most one of three possible values has to be given:
code, ast, or all.

partials (partials aliasing - optional): each entry must be of the type
name_alias ="./alias/path/", where ./ makes reference to dir value. Path
must exist, or error will be prompt. If the tag partials doesn't exist no aliasing
will be possible.

debug (debugging configuration - optional): in order to visualize clearly generated code
in a debugging environment Yarte gives it a tabulated format, and the possibility
to see the number line use a color theme. Options are the following:

number_line (default: false): Boolean, if set to true number lines will appear
in debug-mode.
